I live in Virginia and have been divorced for 9 years. My ex agreed to pay my mortgage as his child support until my house is paid for in 2011. He now says he "has changed his mind" and wants to change our agreement because he isn't making as much money as he used to make. (He quit his job and took a lower paying one.) What are the chances he will be able to do this? He also now has a criminal record of physical abuse againest his new wife and has told our children he might kill himself. Will any of this be taken into consideration if he tries to take me to court to lower his child support ?
